Three-dimensional interstellar dust reddening maps of the Galactic plane [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present new three-dimensional (3D) interstellar dust reddening maps of the Galactic plane in three colours, E(G-Ks), E(Bp-Rp) and E(H-Ks). The maps have a spatial angular resolution of 6 arcmin and covers over 7000 deg$^2$ of the Galactic plane for ...

The Canadian Galactic Plane Survey [PDF]

The Astronomical Journal, 2003
The Canadian Galactic Plane Survey (CGPS) is a project to combine radio, millimeter, and infrared surveys of the Galactic plane to provide arcminute-scale images of all major components of the interstellar medium over a large portion of the Galactic disk.

Prospects for detection of a galactic diffuse neutrino flux

Frontiers in Astronomy and Space Sciences, 2022
A Galactic cosmic-ray transport model featuring non-homogeneous transport has been developed over the latest years. This setup is aimed at reproducing γ-ray observations in different regions of the Galaxy (with particular focus on the progressive ...

Position and Proper Motion of Sagittarius A* in the ICRF3 Frame from VLBI Absolute Astrometry

The Astronomical Journal, 2023
Sagittarius A* (Sgr A*) is a strong, compact radio source believed to be powered by a supermassive black hole at the galactic center. Extinction by dust and gas in the galactic plane prevents observing it optically, but its position and proper motion ...

On a possible corrugation of the galactic plane [PDF]

Symposium - International Astronomical Union, 1970
We have studied the rotation curve of the Galaxy at different heights below and above the equator. In the course of this work we noticed that the maximum brightness temperature of hydrogen oscillates around the galactic plane following a fairly sinusoidal pattern.

Decomposing the Origin of TeV–PeV Emission from the Galactic Plane: Implications of Multimessenger Observations

The Astrophysical Journal Letters, 2023
High-energy neutrino and γ -ray emission has been observed from the Galactic plane, which may come from individual sources and/or diffuse cosmic rays.

GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey II: Galactic plane 345° < l < 67°, 180° < l < 240° [PDF]

Publications Astronomical Society of Australia, 2019
This work makes available a further $2\,860~\text{deg}^2$ of the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey, covering half of the accessible galactic plane, across 20 frequency bands sampling 72–231 MHz, with resolution ...

MeerGAL: the MeerKAT Galactic Plane Survey [PDF]

Proceedings of MeerKAT Science: On the Pathway to the SKA — PoS(MeerKAT2016), 2018
Radio surveys of the Milky Way galaxy have transformed our understanding of star formation\ud and stellar evolution. However, due to strong dependence of “survey cost” on frequency most\ud large area surveys have so far been carried out at low frequencies (? a few GHz).

ARCADE 2 Observations of Galactic Radio Emission [PDF]

, 2009
We use absolutely calibrated data from the ARCADE 2 flight in July 2006 to model Galactic emission at frequencies 3, 8, and 10 GHz. The spatial structure in the data is consistent with a superposition of free-free and synchrotron emission.
